His successors later noticed that sunspots often produce bursts of radiation called solar flares.
To capture the sunspot, the researchers pointed the telescope’s 13-foot mirror—three times wider than any other solar telescope—towards the central area of the star.
This week, the first image of a sunspot from the high-definition Inouye telescope was finally published.
This recent sunspot image was captured on January 28 of this year, and it’s just one part of a bigger series.
The largest solar telescope on Earth has gotten the sharpest glimpse ever of a sunspot.
And Bishop, Colossus, Warpath, Blink, Sunspot, Quiksilver, Stryker and Havoc will all be there too.
For even this great sunspot was but small as compared with the Sun as a whole.
They would not be strictly accurate, because a sunspot could knock all meaning out of any reading beyond two decimal places.
The sunspot cycle has appeared to average 11.2 years in length, and has been called the 11-year cycle.
That is, you cannot connect a particular sunspot group with a particular S-Region.
It means you can only approximately predict the future course of sunspot activity.
